Abstract
To study the concentration change of respirable suspended particulate (RSP) in indoor and outdoor air environment, a new portable sampler (AND-sampler) was made. The sampler could collect particles above 10 microns, 2 to 10 microns, and below 2 microns in aerodynamic diameter separately. The relationship between the airborne particulate concentration in indoor and outdoor air environment varied with the aerodynamic diameter of the particles. The concentration of RSP in indoor air environment increased in proportion to that in outdoor environment. Polycyclic aromatic hydrocarbons (PAH) concentration in airborne particulate also varies with the aerodynamic diameter of the particles. Fine particles below 2 microns in aerodynamic diameter contains high concentration of PAH. The PAH concentration in indoor air environment increases in proportion to that in outdoor air.
